Enhancing Operational Efficiency: Advanced Data Management and Machine Learning Solutions for a Leading Australian Energy Company
Company Background
The client is a publicly listed Australian utility company involved in the generation and retailing of electricity and gas for residential and commercial use. The company operates a significant generation capacity of 10,984 MW, with 85% of this capacity derived from coal-fired plants. This dual-role as both generator and retailer places the company in a unique position within the market, necessitating robust and efficient management of both operational and customer-facing activities.
Problem Statement
The company faced multiple challenges impacting its operations and customer service:
- Debt Management:A significant portion of customers were unable to make timely payments for their energy usage, leading to increased debt. This non-payment resulted in financial strain, causing revenue losses due to bad debt.
- Data Management:The existing data management systems were siloed and inefficient. The need to streamline and centralise data processing was critical to improve decision-making, forecasting, and operational efficiency.
- Operational Efficiency:The disparate data systems and lack of centralised data storage led to inefficiencies in handling operational data critical for market settlements and metering decisions.
- Machine Learning Integration: Existing ML models were used in isolation, lacking integration and streamlining, thus reducing their effectiveness in improving business operations.
Solution
Solution
Data Integration:
Created a centralised data lake using Azure Storage and Databricks to aggregate data from multiple source systems.
Streaming Framework:
Implemented a Spark streaming framework to handle data ingestion, ensuring real-time data availability for critical operational reports.
Data Layers:
Organised data into different layers (staging, raw, integrated, and transformed) for efficient processing and retrieval.
ML Platform:
Established an enterprise ML platform with a feature store accessible to all ML engineers and data scientists, minimising feature duplication and fostering collaboration.
AI/ML Models:
Utilised machine learning algorithms to predict customers with a high propensity to fall into debt, based on transactional and behavioral data from the ERP system.
Data Privacy Compliance:
The solution was hosted within the company’s environment to comply with stringent data privacy policies.
Causal Analysis:
Conducted thorough causal analysis to understand the underlying factors leading to debt, enabling targeted interventions.
Specialist Teams:
Formed specialist teams to investigate and address potential issues identified by the AI/ML models, such as billing errors or faulty meters.
Performance Optimisation:
Leveraged Databricks' optimisation features such as adaptive query execution and dynamic partition pruning to enhance processing speed and resource utilisation.
Data Governance:
Implemented centralised data governance using Databricks Unity Catalog and Collibra to ensure compliance and data integrity.
MLOps Integration:
Developed end-to-end MLOps pipelines using Databricks and Azure DevOps to automate model deployment and monitoring.
